RE: help with hpppl
Add a local variable x:

LOCAL REAL,IMA,N,W,R,C,x;

Store the result of the solve operation in x and add quotes around R and C

x:=CAS.solve({REAL=ZIN_REAL,IMA=ZIN_IMA},{'R','C'});

then RETURN x;

And you get {{0,_(1013904223)}} for an answer. I don't know if it's the right answer, but it's a start.

Here's the code with the suggested changes:
Code:

ZIN_F:=4000000;
 ZIN_REAL:=400;
 ZIN_IMA:=400;

EXPORT ZIN()
BEGIN
LOCAL REAL,IMA,N,W,R,C,x;
 INPUT({{ZIN_F,[0]},{ZIN_REAL,[0]},{ZIN_IMA,[0]}},"IMPEDANCE",{"freq","real","imag"});

 W:=2*π*ZIN_F;
 N:=1+W^2*'R'^2*'C'^2;
 REAL:='R'/'N';
 IMA:=W*'C'*'R'^2/'N';
 x:=CAS.solve({REAL=ZIN_REAL,IMA=ZIN_IMA},{'R','C'});

 RETURN x;
END;
